Why Choose Our GP-Led NIPT Screening?
Expert Consultation Included
Unlike scan-only or retail testing providers, your NIPT is performed in a medical clinic, with a GP available to explain what the test screens for, what results mean (and what they don’t), and next steps if further assessment is needed.
The “Safety-First” Ultrasound Scan
If you have not already had an ultrasound confirming pregnancy viability and gestational age, a scan will be performed prior to taking NIPT blood samples. This ensures the pregnancy is at the appropriate gestation (minimum 10 weeks) and suitable for testing. This step is essential to ensure the accuracy and validity of the results.
Fast, Secure Results
Waiting for results can be stressful. We work with specialist laboratories to ensure results are returned securely within 3–5 working days, wherever possible.
Professional Continuity of Care
If a result indicates higher risk, you will not be left unsupported. Our GP will contact you personally, explain findings calmly and clearly, and coordinate referral to your NHS fetal medicine unit or private obstetrician.
What the NIPT Screens For
Your NIPT screening includes high-accuracy assessment for:
| Condition | Description |
|---|---|
| 99%+ Detection for Down’s Syndromes (Trisomy 21) | The most common chromosomal condition |
| 99%+ Detection for Edwards’ Syndrome (Trisomy 18) | A serious chromosomal condition affecting development |
| 99%+ Detection for Patau’s Syndrome (Trisomy 13) | A rare but severe chromosomal condition |
| Sex Chromosome Conditions (Optional) | Including Turner (XO) or Klinefelter (XXY) syndromes |
| Fetal Gender (Optional) | 99% accuracy, earlier than any ultrasound scan |
This is a screening test, not a diagnostic test. Results indicate risk level only.
How the NIPT Process Works
Ultrasound Dating Scan
We begin with a short ultrasound to confirm pregnancy viability and confirm gestation is ≥10 weeks.
Blood Sample
EA simple blood sample is taken from the mother’s arm — no risk to the baby.
Laboratory Analysis
Your sample is sent to a specialist genetics laboratory for DNA analysis using validated NIPT technology.
Results & Clinical Discussion
Results are typically available within 3–5 working days. A GP contacts you personally to explain the results, answer questions, and discuss next steps if needed. A secure digital report is provided.
The Doctors Laboratory (TDL)
We use The Doctors Laboratory (TDL), one of the UK’s leading independent pathology providers, for all blood and laboratory testing. TDL operates a central laboratory in London, with patient services based in the Harley Street medical district (Wimpole Street), ensuring fast, secure and reliable sample processing.
Results are typically available within 3 working days, although may take up to 1 week.
